AN / JIC Fittings

[WESTERNAERO]

This is the first fitting I've made. -12 AN to -12 O-ring. Notice the large flanged shoulder for the hex. The O-ring style fittings I've found do not have a large enough shoulder to fully close off the O-ring. Also has a taper on the ID for better flow. In the last picture you can see how the o-ring is completely shut off, unlike some that use a standard union and the o-ring is exposed at the flats of the hex.
